Highest Magnification Close-up Lens

The UCL-G55 SD offers the highest magnification among the UCL-G series close-up lenses. The lens provides 4x magnification (scale ratio) compared to the UCL-G165II SD. The lens is specially designed for shooting tiny critters, enabling ultra-macro photography with GoPro cameras.

Change the FOV Setting for Further Magnification

The distance between two sticks represents the shooting range of the UCL-G55 SD when GoPro is set to "WIDE." GoPro cameras have several FOV settings. By using "Linear" or other narrower FOV settings, it is possible to shoot at an even higher magnification. Shooting at a high resolution, such as 4K with "1.4x" zoom, can enlarge the subject even more with relatively less image quality degradation.

Blur-free Focus Stick

The distance between two sticks represents the shooting range of the UCL-G55 SD when GoPro is set to "WIDE." The Focus Stick for UCL-G55 SD has two protrusions representing minimum focusing distance with protrusions at the camera side and the far end of the depth of field with the far side protrusions (tip).

It is easy to take sharp, crisp, high-magnification close-up videos by referring to the Focus Stick and checking the composition on the rear monitor. The Focus Stick rotates 360° and has clicks every 90°, so it can be instantly flipped up when not in use. Vertical installation is also possible. The Focus Stick body is attached to the lens with a retaining screw ring and can be separated from the lens when not necessary.
